When it comes to the technical requirements of the nameplate, it must involve the product standard of the nameplate.Once talked about our country in a quite long period of time, with the word "sign" covers each different application field has the mark product.
Therefore, some relevant standards are only made for machine signage."Signage" has some limitations, and can no longer reflect and represent the development of modern technology.I believe that the standards lag will cause the departments concerned to pay attention to meet the expectations of colleagues in the industry.
Before the introduction of new standards, the standard of "signage" has undergone the following process.
1959: from the former ministry of machinery industry of the People's Republic of China, the ministry issued the standard jb-59 for product signage for the first time;
1964: first revision of the above standard, changed to JB - 64;
1982: jb-82 was reformulated by the former ministry of machinery industry of the People's Republic of China, and the term "nameplate" was used for the first time in the definition of this standard;
1989: drafted the draft of the national standard of signage for public comments;
1991: national standard of the People's Republic of China, signage, GB/t13306-91
The above several stages of the standard, is still aimed at the "machine sign" and the development, although can not reflect the nameplate product overall appearance and the modern situation, but the general technical requirements can be mutually universal.According to the above standards, the technical requirements related to nameplates are summarized as follows.
1. General technical requirements
（1）When the nameplate is assembled with the product, the relationship between the diameter of the fastening hole on the nameplate and the diameter of the fastening nail.

(c) cast steel, rolled sheet steel, etc.;
(d) thermosetting and thermoplastic plastics;
(e) brass sheet /H62 (H68) and other materials may be used for special needs.
B. The nameplate shall be attached to a bonding material that can be firmly attached to a flat, smooth, non-greasy metal or non-metallic surface without activation (such as solvent or heating).
C. The thickness of aluminum plates and other metal materials is recommended as follows: 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 3.0mm, 4.0mm.
All above are for machine signage.
